When flavoprotein transfers electrons directly to the final electron acceptor, hydrogen peroxide is produced. What other consequences might result from electron carriers in the ETC being bypassed? (Hint: See Section 5 Introduction and Appendix A.)

Explanation:

Flavoprotein which are involved in electron transfer are located in inner mitochondrial membrane and accepts the electrons from primary dehydrogenases and transfer to electron transferring flavoprotein dehydrogenase which finally transfer them to coenzyme Q in a normal mechanism.

So if flavoprotein transfers the electrons directly to final electron acceptor it would produce a highly potent oxygen radical "hydrogen peroxide". Apart from this the other effect would be;

it creates acid rain

yes it is weird but true
